Hisonotus charrua Almirón et al., 2006: 88   [original description, type locality: Uruguay, Departamento Tacuarembó, río Uruguay basin, Canãda de Los Penã]. -Reis & Carvalho, 2007: 83 [listed]. Reis & Carvalho, 2009: 35 [included in key].

Hisonotus sp. 2   . Cramer et al., 2007: 54 [included in molecular phylogeny of Loricariidae   ].

Diagnosis. Hisonotus charrua   differs from its congeners, except from H. armatus   , H. leucophrys   , H. leucofrenatus   , H. laevior   , H. notopagos   , and H. taimensis   by the color pattern of the caudal fin, which has a conspicuous hyaline transversal band composed by clear spots (a second posterior band in larger individuals) in a dark background, vs. hyaline areas not forming a clearly defined transversal bands in the middle portion of caudal fin. Hisonotus charrua   is distinguished from H. armatus   , H. leucophrys   , and H. leucofrenatus   by having a narrow naked band without odontodes on the anterior margin of snout, vs. snout completely covered by odontodes; and from H. laevior   , H. notopagos   , and H. taimensis   by the number of lateral plates 23-25 ( Table 2), vs. 25-28 plates; by the number of predorsal plates, 3, vs. 3-4 (modally 4) predorsal plates; and by the number of vertebrae 28-29, vs. 30-32 vertebrae.

Description. This species was recently described by Almirón et al. (2006) and will not be redescribed here.

Distribution and habitat. Hisonotus charrua   is widely distributed in the middle and lower portions of the rio Uruguay basin from the northern rio Ijuí drainage in the Rio Grande do Sul State, Brazil, to the southern río Negro drainage in Uruguay. Besides the limits of the rio Uruguay basin, this species is known from the coastal streams of Uruguay, and from the headwaters of Jaguarão and São Gonçalo drainages in the laguna dos Patos system ( Fig. 22). The species is sympatric with H. ringueleti Aquino, Miquelarena & Schaefer   along its distribution in the middle rio Uruguay basin (Carvalho & Reis, 2009). Hisonotus charrua   is collected together with H. nigricauda   in several streams tributaries to rio Ibicuí and río Negro drainages. This species inhabits a variety of habitats, usually small to medium size creeks with loose stones, and gravel bottom, with median to rapid-flowing water. Collected associated to marginal vegetation composed by grasses or Echinodorus uruguayensis ( Almirón et al., 2006)  

Remarks. No morphological differences were found between populations of Hisonotus charrua   from rio Uruguay basin and the headwaters of rio Jaguarão and rio São Gonçalo drainages in the laguna dos Patos system ( Table 5). Cramer et al. (2007) in a molecular phylogeny of Hypoptopomatinae   + Neoplecostominae, using a mitochondrial gene (cytochrome c oxidase I), included a sample from the laguna dos Patos system population of H. charrua   ( Hisonotus sp. 2   - MCP 25139 View Materials ). According to these authors, the H. charrua   haplotype from the laguna dos Patos system is sister to H. laevior   , while the H. charrua   haplotype from rio Uruguay has a more basal position in a clade composed also of H. taimensis   and H. armatus   . However, there is low resolution in this clade and it seems necessary the inclusion of more samples/genes to unambiguously determine the phyletic status of the H. charrua   morphospecies.
